Cloud migration without downtime — predictable, GDPR-compliant, cheaper to run
A cloud migration only works if your users never notice it. We move your application off Vercel, Firebase, or bare-metal into Terraform-managed infrastructure on AWS, Azure, GCP, or Hetzner — with zero downtime, no vendor lock-in, and typically a noticeably lower monthly bill.
What we migrate
We handle the full migration of your existing application — database, storage, domains, and background jobs. Common starting points are Vercel, Firebase, Heroku, or an aging self-managed server. The target is a cleanly structured cloud on AWS, Azure, GCP, or EU-sovereign on Hetzner, chosen to match your requirements for cost, data protection, and scale.
How the migration runs
We begin with an audit of your current architecture and a concrete migration plan that includes a rollback strategy. The new environment is built in parallel and entirely as infrastructure as code with Terraform and Ansible — reproducible and documented. The actual switch happens through controlled DNS and database cutover procedures, so your application keeps serving traffic throughout. Weekly demos keep you across every step.
The tech behind it
Your workloads run containerized with Docker, orchestrated on Kubernetes where it earns its keep. The whole infrastructure is versioned as Terraform code, with Ansible handling repeatable server configuration. Every state is traceable, reproducible on demand, and cleanly documented for handoff — no manual clicking through consoles that nobody can reconstruct later.
Why Olio
Olio is a boutique agency with senior-level engineering — you work directly with experienced engineers, not a junior team. We are multi-cloud by design and deliberately tie you to no single provider: AWS, Azure, GCP, and Hetzner are all on the table. For EU-sovereign hosting we use Hetzner, GCP EU regions, or AWS Frankfurt — GDPR-compliant, with no data leaving the EU.
What the migration gets you
- Zero-downtime cutover — users never notice the move
- Lower running costs by right-sizing instances instead of paying per request
- No vendor lock-in — the infrastructure is portable as Terraform code
- EU-sovereign, GDPR-compliant hosting on request (Hetzner, GCP EU, AWS Frankfurt)
- Reproducible infrastructure your own team can operate afterward
- Full documentation and a clean handoff — built for long-term operation

Cloud migration questions
What does a cloud migration cost?
It depends on your current architecture — the number of services, the volume of data, and how tangled the dependencies are. A well-scoped migration can usually be quoted at a fixed price. We start with an audit and then give you a concrete figure rather than an open-ended hourly bill. In many cases the migration pays for itself through lower monthly cloud costs.
How long does the migration take?
A reasonably sized application typically migrates in 4 to 8 weeks, including building the Terraform infrastructure, a testing phase, and a safeguarded cutover. Larger systems with many services we stage in phases, so there is always a working intermediate state.
Is it really zero downtime?
We build the target environment fully in parallel and only switch once everything is tested. Coordinated DNS and database cutover procedures keep your application serving traffic during the move, and every step has a rollback plan in case something does not behave as expected.
Which cloud do you migrate to?
Whichever fits you — we are multi-cloud by choice and do not commit you to one provider. AWS, Azure, GCP, and Hetzner are all options. For tight cost control and EU sovereignty Hetzner is often a strong fit; for specific managed services a hyperscaler makes sense. Because the infrastructure is Terraform code, you stay portable later.
Is the hosting GDPR-compliant and EU-sovereign?
Yes. On request we host entirely within the EU — on Hetzner in Germany, in GCP EU regions, or on AWS Frankfurt. Your data stays in the European legal space, with no transfer to third countries.
